Fuel Filter Specs...
« on: May 06, 2015, 12:28:23 PM »
What are the FUEL FILTER SPECS for the following:

Fleet Guard FS 1242 (primary) in Microns...

Cat 175-2949 (primary) in Microns...

And can these two (2) be used as primary main filter substitutes for each other?

Cat 1R-0751, (Secondary) in Microns...

Thank you for your assistance...

No the manufacturers do not make it easy to verify micron rating.

Here is a good source for cross references and for actual specs of Wix replacement filters.  There are not always exactly the same, but a good starting place: http://www.wixfilters.com/Lookup/filterlookup.aspx

From that site:


Fleet Guard FS 1242 (primary): 10 micron

Cat 175-2949 (primary): 3 micron

And can these two (2) be used as primary main filter substitutes for each other? NO, you want a 10-30 micron primary and 2-5 micron secondary (depends on engine specs).

Cat 1R-0751, (Secondary): 2 micron (note, here is where the Wix replacement is different-- shows to be 6 micron).
